What Teachers of Science Need to Know about Models: An overview

The purpose of this article is to provide an overview of the nature of models and their uses in the science classroom based on a theoretical review of literature. The ideas that science philosophers and science education researchers have in common about models and modelling are scrutinised according to five subtopics: meanings of a model, purposes of modelling, multiplicity of scientific models, change in scientific models and uses of models in the science classroom. First, a model can be defined as a representation of a target and serves as a ‘bridge’ connecting a theory and a phenomenon. Second, a model plays the roles of describing, explaining and predicting natural phenomena and communicating scientific ideas to others. Third, multiple models can be developed in science because scientists may have different ideas about what a target looks like and how it works and because there are a variety of semiotic resources available for constructing models. Fourth, scientific models are tested both empirically and conceptually and change along with the process of developing scientific knowledge. Fifth, in the science classroom, not only teachers but also students can take advantage of models as they are engaged in diverse modelling activities. The overview presented in this article can be used to educate science teachers and encourage them to utilise scientific models appropriately in their classrooms.     

An analysis of continuous teacher development in Hong Kong

Education in Hong Kong has developed rapidly since the 70s in parallel with the economic boom. To support such development, the government has invested heavily in initial teacher education and will soon impose professional training and graduate qualifications as prerequisites for entering the profession. Continuous teacher education (CTE), generally regarded as equally important as initial teacher education if not more so, is not given comparable emphasis. This paper aims to study CTE in Hong Kong, including its policy, practice and provision at the system level. Some special features of the system are identified and scrutinized, including ad hoc, policy led, and competence based. The centrally provided CTE is also closely examined in terms of its relevance to the profession, impact on schools, and cost‐effectiveness. The paper ends with a close look at its latest developments, obstacles encountered and prospects.     

Conceptualizing the use of online technologies for gifted secondary students

In an era where technology is advancing at a rapid pace, and where information is readily accessible on the World Wide Web, educators should be capitalizing on these resources for gifted students. This paper proposes a conceptual framework to support individualized and independent learning within a network of peers that will provide challenging interactions through extensive use of online learning. Online resources and technologies promote the exploration of new concepts and sharing of new learning with a group of motivated and “like‐minded” peers.     

Multicultural early childhood education: practices and challenges in Malaysia

Multicultural early childhood education is necessary in a culturally diverse country like Malaysia. Preschool teachers play an important role in implementing multicultural education in the classroom. This paper reports the findings of a self-report questionnaire involving 854 preschool teachers in Malaysia. The preschool teachers disclosed their current multicultural education practices as well as the challenges they encountered when implementing multicultural education. While the majority of teachers claimed that they implemented multicultural education, a closer examination revealed that most of them used the tourist or contribution approach which focuses on only the outward manifestations of a culture when dealing with multicultural education. The transformation or anti-bias approach was used by only a small number of teachers. The teachers identified some challenges in multicultural education implementation, such as lack of instructional resources and the lack of stakeholder support. Thus, it is important to ensure teachers develop more critical understandings of multicultural education through teacher education training and programs. Other efforts to help teachers overcome challenges in implementing multicultural education include producing and developing more instructional materials and learning aids, which are suitable for young children and appropriate for the local context. Preschool teachers also need stakeholders to give more support and to acknowledge the importance of implementing multicultural early childhood education.     

People with Disabilities in China: Changing outlook— new solutions— growing problems

One new child is born with a serious disability every 40 seconds in China. With the number of people with a disability already exceeding 50,000,000 (approaching the size of the whole population of the UK) it can be seen that this rapidly developing third world country is facing a monumental task in rehabilitation and education. This paper does not attempt to offer solutions, but describes the variety and complexities of the problems facing the People’s Republic of China at the present time and makes estimates of its future needs. It also describes some of the ways China is trying to deal with the problems and gives a realistic appraisal of the difficulties faced by academic, clinical, and social welfare authorities.     

Utilization of CSR to build organizations’ corporate image in Asia: need for an integrative approach

Corporate social responsibility (CSR) has been found to be a strong predictor of a favorable corporate image [Gray, 1986. Managing the corporate image: The key to public trust. London: Quorum Books]. Websites have become an essential communication platform [Dawkins, 2004. Corporate responsibility: The communication challenge. Journal of Communication Management, 9(2), 108–119]. This study aims to investigate how CSR can be used in enhancing organizational corporate image. Content analyses of 150 corporate websites of organizations in Asia headquartered in Singapore were conducted, followed by in-depth interviews with public relations (PR) practitioners to examine the motivations behind their CSR engagement. Findings showed that organizations utilized CSR as a means to enhance corporate image via four ways: Engaging in two-way conversations with stakeholders, adopting an inside-out communication approach with employees, recognizing the relevance of other CSR communication channels, and communicating CSR with authenticity. However, some organizations hesitate to use CSR communication to enhance their corporate image because they wanted to avoid being seen as using CSR as a promotional tool.

When ideology meets bottom line: analysis on market competition and ideological bias in newspapers

This study investigated how newspapers adopted partisan branding as a product differentiation strategy under pressure of intense market competition, through cases of conservative dailies in South Korea. Despite academic interest in news media's partisanship, only a few studies attempted to conduct analysis at the organizational level. Drawing on the hierarchy of influences model as a main theoretical framework, the present study examined how partisanship of newspapers was related to the social and economic forces. Evidence demonstrated that conservative bias increased as market competition intensified. Conservative bias was positively associated with the ideological mood of the conservative group, and the revenue decreased as conservative newspapers carried stronger conservative bias. These results will add insight into the prevalence of partisanship in today's media environment.     

The Challenges of Attracting Asian Students to Study Higher Education in Hong Kong

This article reports a commissioned research project on exploring the emerging issues and challenges of attracting Asian students to study in Hong Kong's higher education institutions. Findings reveal the rapidly growing demand for quality transnational education in Asia and the strengths, weaknesses, opportunities and threats of exporting Hong Kong's higher education. The challenges include the need to arrive at a consensus on the aims of internationalisation of Hong Kong's higher education, issues related to promotion strategies overseas, as well as problems of social and multi‐cultural inclusion of non‐local students. Drawing on the research findings, the author suggests going beyond the notion of profit‐oriented vision and exploring the real mission of promoting higher education services overseas that contributes to the enhancement of higher education receivers' learning experiences and preparing students to be future leaders in a humane environment.
